Old immunity is regenerated by the deficiency of leukaemia-biased haematopoietic stem cells
On a possible mechanism of clonal expansion in human hematopoietic stem cell proliferation and repopulation, according to Weinman
Beerman, I. et al. A mechanism of clonal expansion affects the function of hematopoietic stem cells. Proc. There are publications in the Natl Acad. Sci. USA 107, 5465–5470 (2010).
Weissman believes that his team is working on a solution to replenish human blood stem cells. But even assuming ample funding and no unexpected setbacks, it will be at least three to five years before they can begin testing it in people, he says.
Morrison, S. J. & Weissman, I. L. The long-term repopulating subset of hematopoietic stem cells is deterministic and isolatable by phenotype. Immunity 1, 661–673 (1994).
The team will continue studying the effects of the therapy on the mice and find out if it can affect the rates of cancer or inflammatory diseases. “The old versus the young blood-forming system makes a big deal of difference,” says Weissman. There is a difference in the things that make up the bone marrow. It’s a difference all over the body.”
